Application Research on Endoscopic Pseudocapsule-Based Resection for Pituitary Adenomas

Dedicated high-resolution magnetic resonance imaging (MRI) protocols have been proposed to detect pituitary adenoma and accurately guide surgical removal. To accomplish complete PA removal and minimize the impact on pituitary functions, intraoperative navigation was used to identify the tumor pseudocapsule. Depending on different tumor sizes and pseudocapsule development, investigators adopted different resection strategies. The suspicious tissue was sent to the pathology department for histopathology intraoperatively. Long-term postoperative follow-up imaging and endocrine data were used to evaluate tumor prognosis before and after operation. Standardized management and established biobank is critical for pituitary adenomas.
